Hi Jai Pal, you wrote… “run 2 -12,000 A/C-heat units for about 2/3 of the year.  12 amps startup and 1+ amps running amps.”

Maybe there is a much higher voltage these A/C units will run on, but if it  is on 120 V, each would consume 120 W,  which is about 2 old fashioned 60 W lightbulbs. 240 W if the 1 Amp is on a 220-240 V circuit. Hard to imagine A/C units being so efficient as not consuming more than a few incandescent light bulbs. This reference indicates that a single 12,000 BTU A/C on 115 V consumes 13 Amps, or 1495  Watts, which is more believable , about the same as a small hairdryer.

Since solar panels is part of your profession, I feel bad for asking but… Are you sure the power consumption of those A/C units is not at least an order of magnitude more? Maybe you just made a typo when writing “1+ amps running amps” and meant to write “10 amps running amps”.

Please tell me I worry for nothing and all will be fine.  :-)  Thank you for being a big part of this project.

Here Ya go Jerome.. this 15K btu inverter driven mini splits outdoor units shows an RLA of 7.4… LRA of 9.3  

Thanks for the info Mark and Jai Pal. I’m more used to paraglider specs than HVAC, but gather that each of the unit’s outdoor compressor will consume 9.3 A at startup (LRA: Locked Rotor Amps) and 7.2 A after during use (RLA: Rated Load Amps), with a fan adding 0.5 A. If operating with 115 V, we are looking at about 886 W (= 115 V x 7.2+0.5 A) continuous for each outdoor unit. Not sure how much the indoor unit fan consumes, but guessing we are around 1000 W for each unit (outdoor+indoor). So around 2000 W total for 2 A/C units.

Must learn to “go with the flow” and worry less. Knowing we have experts in each field helps trusting this project is in good hands.

David or whoever is sending or receiving on your account, I don’t know about your contractor. I’m not a bathroom contractor but am an Architect and have an excellent memory. So when it comes to requesting donations there is no “Hollywood” money, only a donation request of one USHPA member/pilot who happens to be an actor.  In any case donations currently are about $15,000 towards the structure #3 budget of $58,000. Anything raised beyond the $58,000 can be allocated to other amenities or enhancements of the building for the Club. The idea of lifetime memberships for a donation of $10,000 has been brought forward by several CSS members and seems to be getting some traction. So if you can support the project in whatever way is possible for you that would be great. Good luck to us all. Regards, and I will do the same. Be well.

Jai Pal, do you really think that mine and Dave’s accounts have been hacked? You should notify the webmaster if you believe this to be true.

It would be nice to have an update on the shade structure.
